The D casino takes Southwest or Spirit boarding passes issued within 24 hours. You can use EITHER the say hi to Matthew from YouTube or Richard Wilkes to get an extra $25. Apparently you can only use them once. You can also show the pass at El Cortez to get a $25 match play. At the D, I split aces and lost both hands but at El Cortez I got a BJ so I am $100 up plus the $8 I won on the $10 free slot play. Headed the
Trop now to get my daily $25 free play.
